Fant du ut hva som var feil? Har samme problemet selv. 3 pins vifte som ikke går rundt.
Kan tilføye følgende som jeg fant ute på verdensveven:
"The electric fan is controlled by a pulse width modulated signal from the
ECM.
The fan is activated based on the ECM calculation (sensing ratio) of:
• Coolant outlet temperature
• Calculated (by the ECM) catalyst temperature
• Vehicle speed
• Battery voltage
• Air Conditioning pressure (calculated by IHKA
and sent via the K-Bus to the ECM)
Activation of the electric fan:
When the vehicle is first started the fan is activated briefly (20% of maximum speed), then
it is switched off. This procedure is performed for diagnostic purposes.
The voltage generated by the fan when it slows down (it becomes a generator at this time)
must meet the power output stages programmed criteria. This will confirm the RPM of the
fan, if this is not met the signal wire from the output stage is switched to ground and a fault
is set in memory."
